Malaysia possesses about 1.56 million ha of Peat Swamp Forest (PSF). The PSF safeguard enormous biological diversity, while providing crucial benefits for the sustainable development of human communities. Numbers of threatened plant species are associated with the PSF, including the commercially important Gonystylus bancanus timber. To prevent significant losses of biodiversity, it is important to manage the PSF for both biological conservation and sustainable use. Equally important is to restore all degraded PSF in an attempt to ensure the PSF ecosystem is suitable for the vegetation to grow and rehabilitate back to the normal condition. Prior to plan any forest restoration program, there is a need to properly map the degraded PSF in order to estimate the forest conditions and determine the vegetations status. Most of the time this need to be done at a landscape level and requires a technology that can provide accurate, timely and reliable information for the planner to make decision. This paper describes a study using geospatial technology in combination with ground survey to classify the degraded PSF in South East Pahang Peat Swamp Forest (SEPPSF), Malaysia, into different degree of vegetation classes. With map accuracy of about 83%, the technique proved to be useful in delineating the different degree of PSF degradation from which the information can be used to properly plan forest restoration program in the area. The final output which is in the form of map can be used in developing a Restoration Master Plan for the degraded PSF areas.

Tuberculosis causes high morbidity and mortality. However, Korea still has the highest tuberculosis (TB) incidence and mortality among OECD countries despite decreasing incidence and mortality due to the development of modern medicine. Korea has now implemented various policy projects to prevent and control tuberculosis. This study analyzes the effects of public-private mix (PPM) tuberculosis control program on treatment outcomes and identifies the factors that affecting the success of TB treatment. We analyzed 130,000 new tuberculosis patient cohort from 2012 to 2015 using data of tuberculosis patient reports managed by the Disease Control Headquarters. A cumulative incidence function (CIF) compared the cumulative treatment success rates for each factor. We compared the results of the analysis using two popular types of competition risk models (cause-specific Cox's proportional hazards model and subdistribution hazard model) that account for the main event of interest (treatment success) and competing events (death).

Purpose: The purpose of this study was to identify the Health Promotion Life Profile of normal-weight and obese children, and factors related to obesity in elementary school children, and provide basic data for the development an obesity management program for these children. Method: The survey participants were 878 fourth to sixth grade elementary school children in Gwangju. $x^2$-test, t-test, ANOVA and multiple logistic regression with the SPSS program were used to analyze the collected data. Results: The Health Promotion Life Profile showed significant differences between normal-weight and obese groups according to food habits (t=3.305, p= .001) and exercise habits (t=-4.065, p=< .001). The Health Promotion Life Profile of obese children was also significantly different according to interest in weight control (F=3.044, p= .050), regular breakfast (F=3.699, p= .014), regular meals (F=6.868, p= .002). The multiple logistic regression analysis, showed that factors in obesity were significantly different according to gender, interest in weight control, fast eating, overeating and predilection for some food. Conclusion: The results of this study suggest that items on Health Promotion Life Profile such as food habits and exercise habits should be included in education programs to prevent obesity in elementary school children.

After kidney transplantation, immunosuppressive medication is essential to enhance the quality of life and survival of the transplanted patient. To promote the medication adherence, subjects are required to have converged attitude with open mind. Medication adherence will depend on the attitude of the psychosocial characteristics and treatment guidelines. The purpose of this study was to identify the specific types and characteristics of medication adherence in the view of kidney transplanted patients. Q-methodology, a technique for extracting subjective opinions, was used. Forty participants completed the Q-sort activity, rating each statement relative to the others. The collected data were analyzed by QUANL PC program. Four types of medication adherence of kidney transplanted patients were identified: 'positive lifestyle management type', 'vigilant appearance management type', 'somber oblivion type', 'vigilant family support type'. Through the identification of attitudes to medication adherence, repeated and individualized medication adherence program will help to prevent graft rejection.

In this study, we researched a pendant-type aspherical optical system, which could be applied to street lighting and security lighting in Europe. The goal of this research was eco-friendly artificial lighting that could be used for the one-to-one replacement of ordinary lighting. LED lighting was miniaturized by using one COB LED Module and one aspherical optical system, which could control the luminosity of the LED. Through the aspherical optical system, the light distribution angle could be controlled in a range of $140^{\circ}$ for the X-axis and $40^{\circ}$ for the Y-axis. This means that this optical system is appropriate for catenary-type lighting, which is widely used in Europe on both narrow and broad roads. The performance was determined using a lighting simulation program. This lighting system simulation showed that road rates M4 and M5 could be satisfied, with the condition of a 13-m height and 50-m distance (U0 and TI). The simulation program estimated that light pollution, which disturbs sleep, could beeliminated in the European streetlight case. Determining methods for the light distribution control, performance, and optimal lighting setup conditions is very important to prevent light pollution. Moreover, the initial step of developing the lighting system design and post management will require an effort with much analysis.

BACKGROUND: Large amount of veterinary antibiotics have been used in the livestock industry to prevent diseases and promote growth. These antibiotics are excreted through feces and urine in unchanged form and reach to agricultural fields via application of the livestock manure based composts. The purpose of this study was to evaluate the occurrence of tetracyclines-resistant bacteria in the soil received livestock manure compost for a long term. METHODS AND RESULTS: Tetracyclines (tetracycline TC, chlortetracycline CTC, and oxytetracycline OTC) resistance bacteria in the soil of rice-onion field applied pig manure compost (PM), in the soil of grass-rye field received cow manure compost (CM), and in the soil of rice field applied inorganic fertilizer (NPK) were determined. The soil received livestock manure composts clearly showed higher number of TC, CTC, and OTC resistance bacteria compared with the soil treated with inorganic fertilizer. The antibiotic resistant bacteria recovered appeared at 80 mg/L of tetracyclines was identified 1 specie, 6 genera 7 species, and 6 genera 7species in the soils received CM, PM, and NPK, respectively. The dominant resistant bacteria with the CM and PM application were Ochrobactrum and Rhodococcus. CONCLUSION: The application of livestock manure compost in the agricultural field is likely to contribute the occurrence of antibiotic resistance bacteria in the agricultural environment.

Emergency preparedness plan (EPP) is the systematic management of activities that involve a material degree of risk of loss or other damage to the surroundings (people, property and environment), and the boundary of accident recovery plan (ARP). The main purpose of the program is to provide a safety management system to each facility in order to enable to prevent accident and to control accident immediately. The EPP includes not only typical safety-related documentations such as material safety data sheet (MSDS), standard operation procedure (SOP), emergency response plan(ERP). EPP is established basis of the preliminary safety analysis involving risk identification, assessment and prevention plans. The program is also helpful for government or related agencies to control a number of accidents in small-scale companies in the whole country.
